Description
Provides management information definitions
for the User-based Security Model (USM) for
SMNPv3. The SNMPv3 architecture
introduces the User-based Security Model
(USM) for message security.
The USM module decrypts incoming
messages. The module then verifies the
authentication data and creates the PDUs. For
outgoing messages, the USM module
encrypts PDUs and generates the
authentication data. The module then passes
the PDUs to the message processor, which
then invokes the dispatcher.
The USM module's implementation of the
SNMP-USER-BASED-SM-MIB enables the
SNMP manager to issue commands to manage
users and security keys. The MIB also enables
the agent to ensure that a requesting user
exists and has the proper authentication
information. When authentication is done, the
request is carried out by the agent.
The SNMP-USER-BASED-SM-MIB is
described in RFC 3414.
User configuration is applicable only
Note
for SNMPv3; SNMPv1 and SNMPv2c
use a community string match for user
authentication.
